Explore our fast, free, browser-based tools for trimming, noise reduction, and voice effects.
Non-destructive, high-precision audio editing operations built on the Web Audio API.
Select any region on the waveform and trim to keep just that section. Zoom up to 600 px/s for millisecond-accurate cuts.
Highlight mistakes, awkward silences, or stumbles and remove them with one click. Automatically joins the remaining audio seamlessly.
Divide long podcast episodes, live sets, and concerts into separate clips. Manage and export each track individually.
Adjust playback rate from 0.5x to 2.0x in real-time. Speed up voice memos or slow down complex musical parts with baked export.
Check your microphone volume, frequency response, and background noise levels in real-time before recording.
AI-powered spectral denoisers and studio mastering tools to make speech crystal clear.
Eliminate steady-state mic hiss, room fan noise, and ambient hum using in-browser TensorFlow spectral gating without uploading files.
One-click professional audio mastering that applies multiband dynamics compression, high-shelf clarity air boost, and normalization.
Amplify faint phone recordings, distant lectures, and quiet speech tracks up to 4x loudness with real-time clipping detection.
Combine background noise suppression, breath cutting, and vocal EQ to make dialogue sound broadcast-ready.
11 real-time voice filters to transform vocals for TikTok, YouTube Shorts, and creative media.
Pitch shift vocals upward into squeaky cartoon chipmunk voices for humorous videos and gaming clips.
Ring modulation DSP that turns speech into sci-fi cyborgs, synthetics, and metallic vocoder vocals.
Deep pitch shifting and sub-harmonic resonance creating scary movie villain, demon, and giant voices.
Algorithmic room and hall impulse simulations providing acoustic depth and spatial atmosphere to dry audio.
Universal compatibility across all major digital audio containers and codecs.
Three simple steps from raw recording to polished audio — no software installation needed.
Drag and drop any audio file directly into the editor, or click Import. Your audio renders instantly with high-DPI waveform visualization.
Select regions on the waveform to trim, cut, or split. Apply voice effects, boost volume up to 400%, or use AI Noise Reduction to clean background static.
Export your master as lossless WAV or compact MP3. All edits, speed changes, and effects are baked into your final download.
Fast, private, free, and accessible on every device.
Unlike cloud audio editors, your files are never uploaded to remote servers. All signal processing and AI noise reduction run locally in your web browser.
No account registration, no subscriptions, no watermarks, and no artificial file size limits. All tools and voice effects are free forever.
Runs smoothly in Chrome, Safari, Firefox, and Edge across desktop, laptop, tablet, and mobile devices with zero plugins.
Waveform zooming up to 600 px/s, spectral noise reduction, and studio dynamic compression with an interface anyone can master in seconds.
Step-by-step guides to help you master audio editing, mastering, and cleanup.
Quick answers to common questions about editing audio online.
Yes, 100% free. There are no trials, no premium tiers, no watermarks, and no file size limits. Every feature — including AI Noise Reduction, 11 voice effects, Studio Enhance, metadata editing, and WAV/MP3 export — is available to all users at no cost.
No. Your audio files never leave your device. All editing, effects processing, and even AI Noise Reduction run entirely inside your web browser using the Web Audio API and TensorFlow.js. We have no servers that receive, store, or process your audio. Your recordings remain completely private.
OnlineAudioEdit supports importing MP3, WAV, M4A, AAC, OGG, OPUS, FLAC, WEBM, and AIFF files — essentially any format your browser can decode. For export, you can save your finished audio as WAV (lossless quality) or MP3 (smaller file size). A "Match import" option tries to match your original format automatically.
Our AI Noise Reduction uses TensorFlow.js to perform spectral gating directly in your browser. It learns a "noise profile" from either the first half-second of your recording (auto-detect) or a region you manually select. Then it removes that specific noise pattern — like air conditioner hum, fan buzz, or microphone hiss — while preserving voices, music, and the sounds you want to keep.
Yes. OnlineAudioEdit is fully responsive and works on any modern mobile browser including Chrome, Safari, Firefox, and Edge. The interface automatically adapts with a slide-out sidebar and touch-friendly controls so you can edit audio comfortably on smaller screens.
Trim keeps only the selected region and removes everything else — perfect for extracting a highlight clip. Cut removes the selected region and joins the remaining parts seamlessly — great for deleting mistakes or awkward pauses. Split divides your audio into separate clips at the selection boundaries so you can work with each part independently.
